CHARLES A. MAXFIELD, OF NEW YORK, N. Y., Assieivon' TO JACOB WAL- LACE, TRUSTEE, or SAME PLACE.

PRESERVING, STRENGTHENING, WATERPROOFING, AND GLOSSING TEXTILE FABRICS, INCLUDING PAPER.

SPECIFICATION forming part of Letters Patent No. 328,956, dated October 27,1885.

Application filed May 23, 1885. Serial No. 166,496.

To aZZ whom, it may concern.-

Be it known that I, CHARLES A. MAXFIELD, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Preserving, Strengthening, WVaterproofing, and Glossing Textile Fabrics, including Paper, of which the following is a specification. I

My present invention relates to preserving, strengthening, waterproofing, and glossing textile fabrics, including paper; and it consists in the application to one of the surfaces of such fabricspreferably its exposed surface-of a coating of the natural wax known as ozocerite. i

In my Patent No. 278,443, granted May 29, 1883, I described a new article of manufacture consisting of paper saturated or covered on both surfaces with the natural wax known as ozocerite. For many uses-some of which are enumerated in said patentthis is a desirable commodity; but for other uses it has practically no value. Besides, paper or other material treated as proposed in this applica tion costs less than the same material which is treated by being saturated or covered on both surfaces, and in cases where nothing is to be gained by saturating or covering both surfaces the present plan would obviously supersede the other.

I have treated wall-papers in the. manner now described, so as to render them impervious to water, and thus enable them to be washed the same as a painted surface. By the application of the ozocerite to wall-papers their colors are set, so that they not only do not rub off, but all liability of their affecting the health of personswhich sometimes happens where the cheaper grades of papers are usedis counteracted. The surface of wall-papers thus treated may be glazed or not, according to the requirements of the trade. If an unglazed surface is desired, it is only necessary to apply a low degree of heat to the unprepared surface of the paper, after having applied the ozoce- It is obvious that if wall-papers were saturated or covered on both surfaces it would be practically impossible to make them adhere to the walls by the use of (No specimens.)

the paste ordinarily employed for such purpose; besides, the cost of treatment of the paper would be largely increased.

VValLpapers treated in the manner posed would be quite indestructible, and the cheaper grades of paper would be almost as desirable as the finer qualities.

My invention may also be used in the manufacture of pictures printed in colors-such as chromos and chromo-lithographs-the ozocerite in such cases serving to preserve the surface of the picture and rendering it capable of being washed without detrimentally affectlng it.

I contemplate preparing paper ofall descriptions in the manner herein explained-as, for instance, paper designed for use in various mercantile pursuits, such as the confectionery, dry-goods, fancy goods, and hardware branches of trade, and also paper to be used for building and roofing purposes.

The qualities of ozocerite are such that paper prepared therewith in the manner explained will not impart to the article inclosed within it any discoloration or disagreeable odor.

Textile fabrics of various kinds may be rendered water-proof when treated as herein explained, and when thus prepared they may be used as substitutes for rubber water-proof goods and made up into garments for various uses.

In carrying out my invention I may use any suitable machinery; but I prefer to employ the apparatus and method which form the sub- Jects of applications for patents filed by me of even date with this application. In the applications referred to I have fully described a mode of preparing the paper or other fabrics. So far as this patent is concerned, it is sufficient if I state that the ozocerite may be applied to the paper, cloth, or other material by a hand-brush; but this process would be tedious and expensive.

The best method of applying the ozocerite that I am now aware of is set forth in the applications above mentioned, and to which reference is here made for an explicit description thereof.

Having thus described my invention, what I now pro claim as new, and desire to secure by Letters Patent, is-

1. As a new article of manufacture, textile fabrics,including paper, having applied to one 5 surface only thereof the natural wax known as ozocerite, 7 whereby said fabrics are strengthened, &c., and their said surface rendered water-repellent, substantially as set forth.

2. As a new article of manufacture, wall- 10 paper having its face or exposed surface treated with the natural Wax known as ozocerite, substantially as and for the purpose set forth.

Signed at New York, in the county of New York and State of New York, this 19th day I 5 of May, A. D. 1885.

CHARLES A. MAXFIELD.
